Which property was used to write the equation in step 2?
step 1: 5(x-7) = 55
step 2: 5x-35 = 55
step 3: 5x = 90
step 4: x= 18
a) distributive property
b) addition property of equality
c) subtraction property of equality
d )division property of equality

The property that was used to write the equation in step 2 is option A) distributive property

Given that,

So here we have to use the distributive property i.e.

So,  

5x - 35 = 55

Therefore we can conclude that The property that was used to write the equation in step 2 is option A) distributive property

A

Step-by-step explanation:

Given

5(x - 7) = 55, then using the distributive property, that is

a(b - c) = ab - ac, then

5x - 35 = 55

the answer is d. 75%
